Notes:
Sistar19 is the only subunit
T-ara is the only group to have both 2 songs on the chart and have them top the year consecutively

This list is just year end chart data since that's the only way Rough is over Cheer Up for 2016 which in all this doesn't show much as songs coming out earlier have an advantage over those coming out later so it won't always show what will be the biggest hit in the long run
